He played in 2 extremely hitter friendly environments the last 2 years. The Eastern League and PCL are very hitter friendly and the numbers posted there should be taken with a grain of salt period.
When he was hitting in the SAL and FSL where both environments are extremely pitching friendly he did not do as good.
...hence why I think he is more of a guy that will hit somewhere between what he did in those different places.
...and yes the fact that their are not many good offensive catchers in baseball is what makes him valuable as a guy who may post an OPS around .775-.825.
